Abstract: A lumbosacral support includes an elastic belt adapted to be worn around a person's waist and includes Velcro fasteners at its ends. The belt carries a double layer foam pad adjacent the middle thereof which is adapted to lie against the wearer's lower back. A vertically extending trough-like groove is cut away from the central portion of the pad. The pad directly overlies the wearer's spine whereby when the wearer presses against a seat back, the pad puts pressure on the supporting lumbosacral musculature on either side of the spine but does not put pressure directly on the spinal column.
